Why my WACKER Group PT 6LT engine does not start?
- B
  Brooke PopeAug 1, 2025
  If your WACKER Group Water Pump engine doesn't start, it might be due to several reasons. The fuel tank could be empty, or the wrong type of fuel or old fuel might have been used. In such cases, drain the tank, change the fuel filter, and fill it with fresh fuel. Other potential causes include an unprimed fuel system, loose or corroded battery connections, a dead battery, low electrolyte, low engine oil level, an overheated engine, a defective ignition switch or throttle solenoid, loose or broken electrical connections, or a faulty engine.
